Alpine Peatland Flux Data Collection

This release consists of flux tower measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer using eddy covariance techniques. Data were processed using PyFluxPro (v3.4.15) as described by Isaac et al. (2017). PyFluxPro produces a final, gap-filled product with Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER).

The Alpine Peatland flux station was established in 2017 at Heathy Spur I, an alpine sphagnum bog on the Bogong High Plains recognised by Parks Victoria as a reference ecosystem for this endangered ecological community. The vegetation is dominated by the peat-forming moss Sphagnum cristatum, as well as typical peatland species including candle heath (Richea continentis), alpine baeckea (Baeckea gunniana) and rope rush (Empodisma
minus). The Alpine Peatland tower typically experiences a mild growing season from October to June and 2-3 months of snow cover from July to September.

本数据集包含采用涡度协方差（eddy covariance）技术获取的地表与大气边界层之间能量与物质交换的通量塔观测数据。所有数据均按照Isaac等人（2017年）所述方法，使用PyFluxPro（v3.4.15）进行处理。PyFluxPro可生成经间隙填充的最终数据集，将净生态系统交换量（Net Ecosystem Exchange, NEE）划分为总初级生产力（Gross Primary Productivity, GPP）与生态系统呼吸（Ecosystem Respiration, ER）。
阿尔卑斯泥炭地通量站于2017年在Heathy Spur I建成，该站点坐落于博贡高平原的一处高山泥炭藓沼泽，被维多利亚州公园管理局（Parks Victoria）认定为该濒危生态群落的参照生态系统。该站点的植被以形成泥炭的冠层泥炭藓（Sphagnum cristatum）为优势种，伴生有泥炭地典型物种，包括蜡烛欧石楠（Richea continentis）、高山贝卡木（Baeckea gunniana）以及细茎绳莞（Empodisma minus）。阿尔卑斯泥炭地通量塔所在区域通常具有10月至次年6月的温和生长期，以及7月至9月共计2至3个月的积雪覆盖期。
